I saw changes when using values up to 120%, but then I tried 130%, 140% and 150% and I didn't see any further changes. I wonder if 120% is the max that this setting has an effect on the system.

I saw other's have changed up to 120% in the archives, but didn't find more than that. Also saw somewhere that Doc was saying someone's car didn't show results when changing Secondary - I wonder if that was also with these higher values?

So anyone see >120% actually result in differences?

Maybe your injectors are maxed out at 120%

I've been able to fatten out with as little as +3% PFT. Just curious why you'd need 120% unless you're venturing into other hardware.

ADDED:
I also see good response to Accel Pump. Never saw any change with Secondary.

just a question: with the secondary pump at 120% do u smell gas in cabin

I'm playing around with something on my car. If I change Primary Fuel by +8%, I get (richer) to an O2Voltage level that I like.

Doing this, however, appears to be hurting my A/F at cruise as well, as I am seeing horrible MPG (15-16mpg).

Therefore, I decided to try changing Secondary instead, hoping that would only alter my WOT A/F. Changing Secondary, however, didn't get me as rich as I had been before (when I was at +8% Primary instead).

So, as you can see, my car is capable of the fueling (I'm not maxing out injectors, etc). I'm able to achieve the O2V I want with Primary, but I can't seem to get there with Secondary changes alone. Honestly, I didn't test with 100% Secondary, so I can't for sure say that I saw changes from 100% to 120%, but I know others have seen changes and posted such data.

the ME7 docs seemed to indicate these were "fine tuning" proceedure adjustments based on locale and other crap. The tuning shoud be done in the table transitions for big changes like that I'd say.

Whenever I fatten up w/ PFT my mileage goes to hell too. I'm trying to see what Accel Pump does comparatively as my near-redline O2s are good but my early-pull 4-5k O2s are lean.

lean regardless. With that said, I've never heard of anyone running over 120%. I know Nick Gustas run/ran 120% secondary and documented increased WOT 02 votlages.

What have you done with accel pumps and what have you noticed?

I'd be very interested in knowing whether you can dial in your WOT o2's with secondary or secondary + accel. I run into the same problem as you...fattening up WOT throws off partial horribly.
